Description

Self-priming cyclone water curtain paint mist treatment device

technical field

The utility model belongs to the technical field of environmental protection, and in particular relates to a self-suction cyclone paint mist processing device.

Background technique

Paint mist removal is a treatment process for exhaust gas in industrial production. It can remove paint mist and paint droplets in the exhaust gas to make the exhaust gas cleaner. The existing paint mist removal devices include pumping water curtains and spraying devices. , Paint mist cotton filter, filler filter and other methods. The pumped water curtain is most used in the paint mist removal process. When the spray paint exhaust gas enters the pumped water curtain from the air inlet, the water pumped into the water tank by the water pump forms a water curtain along the edge of the tank, and the surface of the water curtain rises. Forcefully bring the paint mist and paint droplets in the exhaust gas into the water to remove the paint mist and paint droplets in the exhaust gas. The purified waste gas is separated by the solid, liquid and gas separator and then discharged.

The traditional water curtain uses a water pump to pump the water in the circulating water tank into the water tank, and the water in the tank overflows to form a water curtain along the water guide plate to remove the larger particles of paint mist in the paint mist. It has a simple structure and high production capacity. Large, small size, low investment, easy operation and maintenance, low operation and maintenance costs and other significant advantages, widely used in chemical industry, petroleum, metallurgy, building materials, mining and other industries. Its disadvantages are low removal efficiency, easy clogging of the water pump, no scraping system, etc.

Utility model content

In order to solve the defects of the paint mist removal device in the prior art, such as low removal efficiency, easy blockage of the water pump, and no slag scraping system, the utility model provides a self-suction cyclone water curtain paint mist removal device.

The technical solution adopted by the utility model is: a self-priming cyclone water curtain paint mist treatment device, including a bracket, a circulating water tank is arranged on the bracket, and the upper part of the self-suction cyclone water curtain paint mist treatment device is set There are baffle water filtration, solid, liquid and gas separation chamber and gas distribution outlet, the middle part is equipped with gas mixing device and return water pipe, and the lower part is equipped with slag scraping system; the gas mixing device includes cyclone inlet, gas mixing throat and cyclone outlet , The gas mixing device is equipped with a medicament adding port.

Further, the cyclone inlet is a square cone, the gas mixing throat is a rectangular straight pipe, and the cyclone outlet is a square inverted cone;

Further, a quadrangular truss-shaped gas collection hood is provided below the gas distribution outlet, the gas collection hood is fixedly connected to the bracket, and the gas distribution outlet is fixedly connected to the gas collection hood;

Further, the medicament addition port is installed on both sides of the gas mixing throat.

Compared with the prior art, the beneficial effect of the utility model is: when the paint mist passes through the self-priming cyclone water curtain paint mist removal device of the utility model, after the interaction of the cyclone, the water curtain, the siphon effect and the turbulent flow, and finally The solid, liquid and gas separation device separates to achieve a better effect of removing paint mist. The removal efficiency of paint mist is high, the operating cost is low, and it is easy to operate.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described.

Embodiment 1,

A kind of self-priming cyclone water curtain paint mist treatment device, comprises support 11, is provided with circulating water tank 1 on the support 11, and the top of described self-priming cyclone water curtain paint mist treatment device is provided with baffle water filter 8 and Solid, liquid and gas separation chamber 9 and gas distribution outlet 10, the middle part is provided with gas mixing device 12 and return water pipe 6, and the lower part is provided with slag scraping system 2; said gas mixing device 12 includes cyclone inlet 3, gas mixing throat 4 and The cyclone outlet 7 and the gas mixing device 12 are provided with a medicament addition port 5 .

Embodiment 2,

A self-priming cyclone water curtain paint mist treatment device, the cyclone inlet 3 is a square cone, the gas mixing throat 4 is a rectangular straight pipe, and the cyclone outlet 7 is a square inverted cone; Example 1 is the same.

Embodiment 3,

A self-priming cyclone water curtain paint mist treatment device, a quadrangular platform-shaped gas collection hood 13 is provided below the gas distribution outlet 10, the gas collection hood 13 is fixedly connected with the bracket 11, the gas distribution outlet 10 is connected to the gas collection Gas shield 13 is fixedly connected; Others are the same as embodiment 1.

The slag scraping system 2 includes two or more rollers 14 and a conveyor belt. A scraper 15 is provided on the conveyor belt, and one roller 14 is connected to the power output end of the motor to drive the conveyor belt to run.

When using the utility model, the utility model is fixedly installed in an appropriate position, and the air distribution outlet 10 is connected with the exhaust system; the pipeline of the medicament addition port 5 is connected with the external medicament box through the pipeline. The water in the circulating water tank can be recycled and replaced regularly.

The working principle of the utility model is: since the induced draft fan at the rear end of the equipment forms a negative pressure at the cyclone inlet 3, the paint mist, waste gas and water on the water surface of the circulating water tank 1 form a cyclone and enter from the air inlet 3, and enter the gas mixture through conical compression. Throat 4, paint mist, exhaust gas and water go upward along the air mixing throat 4, and when passing through the air mixing throat 4, the paint mist, exhaust gas and water vapor are fully collided and mixed; due to the inverted cone shape of the cyclone outlet 7, the pressure is suddenly released. The upper part of the air-mixing throat 4 forms a local negative pressure, where the paint mist, exhaust gas and water are fully mixed; after the adhesive is added to the medicament addition port 5, it enters the solid-liquid-gas separation chamber 9 from the cyclone outlet 7, and the gas passes through the cloth The gas outlet 10 is discharged, the solid and liquid flow into the water tank through the return pipe 6, and the water flow overflows to form a water curtain. Thereby the separation efficiency of the solid, liquid and gas separation chamber 9 is greatly improved.
